I think it's complementary. Age-friendly cities are based on the principle of the social involvement of seniors and the information of seniors. The basic principle is that an age-friendly city provides a balance between the health, social involvement and safety of seniors. I think it's really fundamental. From that perspective, an age-friendly city is friendly for all ages. It is organized so that there are important ties and relationships between the generations.
